I was thinking of building one,.. have the plans for an electric one with a 114 or so inches!
and running 6 geared speed 400's
I'd like to shrink it down to about 80" and use GWS IPS geared motors with 3-blades. but right now, I'm tapped for funds & can't even afford the reduction of the plans...
It also has some foam parts I'll have to design out,.. not much of a foam-guy. Perhaps these 3-views will "inspire" Me!
